I've had a Galaxy Nexus for just over a year now (Just outside of warranty) and I've found that there is some burn-in on the display. A feint qwerty keyboard shows all the time on my screen, and the whole display has a sorta greyish tint to it. I had no idea you could get this problem on LED displays. I thought it was limited to Plasma only.
I now I can't really repair this unless I replace the entire screen, which will probably cost an absolute bomb, but has anybody had this issue before with these types of screens?
My phone uses a HD Super AMOLED with PenTile screen, which I thought was meant to be the most high-end kind of mobile display you could get.
My theory is that the actual phone itself can get quite hot sometimes, and this is the reason why there's burn in. I'm thinking the heat could have scorched the white piece of paper used in the display? Or am I completely on the wrong track here?
I have seen a Samsung Vibrant with screen burnt, not retention. I could see the background image on all screens no matter what I did. Like like a laptop/desktop LCD screen burnt issues can happen on phones. Probably had your screen set to stay on to long??
And like someone else says, my phone has the screen retention issue. Where at times you can see a faint image of the previous screen for a few seconds. But then it goes away. Only see it faintly on light screens and never while playing games. And like i said, only lasts a second or 2 so it really doesnt affect the phone's usage/performance any.
